| Summary: | This data set includes the materials required to reproduce the figures and tables presented in the study: "A 21st Century Warming Threshold for Sustained Greenland Ice Sheet Mass Loss". The data consist of: Maps of annual historical and projected surface mass balance (SMB) of the Greenland ice sheet (GrIS) from RACMO2.3p2 at 1 km spatial resolution in NetCDF format. smb_rec.1950-2014.BN_RACMO2.3p2-CESM2-Historical.1km.YY.nc: annual cumulative GrIS SMB (kg m-2 or mm w.e. per year) from RACMO2.3p2 forced by CESM2 for the historical period 1950-2014, further statistically downscaled to 1 km spatial resolution. smb_rec.2015-2099.BN_RACMO2.3p2-CESM2-SSP5-85.1km.YY.nc: annual cumulative GrIS SMB (kg m-2 or mm w.e. per year) from RACMO2.3p2 forced by CESM2 under a high-end warming scenario SSP5-8.5 for the period 2015-2099, further statistically downscaled to 1 km spatial resolution. Icemask_Topography_lon_lat_average_1km_GrIS.nc: mask file including an ice mask (Promicemask) separating Greenland's peripheral glaciers and ice caps (values 1 and 2) from the main ice sheet (value 3), surface topography derived from the GIMP DEM, and longitude/latitude coordinates on the 1 km grid. NB: the NetCDF files above use a Polar Stereographic North (EPSG:3413) projection with a horizontal resolution of 1 km x 1 km. The reference point is located at 45ºW longitude and 70ºN latitude. Time series of historical and projected annual GrIS-integrated SMB (Gigatons or Gt per year) and annual mean GrIS temperature (TGrIS; K) from RACMO2.3p2 at 1 km spatial resolution in ASCII format. SMB_TGrIS_RACMO2.3p2-CESM2_Historical_1950-2014.dat: time series of annual GrIS-integrated SMB (Gt yr-1) and mean TGrIS (K) from the CESM2-forced RACMO2.3p2 simulation for the historical period 1950-2014. SMB_TGrIS_RACMO2.3p2-CESM2_SSP5-8.5_2015-2099.dat: time series of annual GrIS-integrated SMB (Gt yr-1) and mean TGrIS (K) from the CESM2-forced RACMO2.3p2 projection under a high-end warming scenario SSP5-8.5 (2015-2099). Time series of historical and ... |
